Book Description
The goal of any structural design process is to produce a safe design that meets all the design codes requirements, while trying to minimize the cost of the design. Until recently, this process was based on the judgment of the designer. Optimization in structural design is a recent concept that has been introduced and used in the last couple of decades to find the optimum designs based on mathematical algorithms and techniques that is more accurate compared to human judgment. The research related to structural optimization is still scattered and limited, with no effective application in real life design process. This study introduces an optimization model to minimize the cost of reinforced concrete (RC) highrise structures, that include flat slab system. The model is based on neural networks optimization technique, structural analysis principles, code provisions for designing of RC elements, and seismic design requirements. The model automates the design of the structural elements (slabs, beams, columns, and shear walls), which will reduce the time previously consumed to accomplish this process, while minimizing the cost. The model is applied to a real-life structure, where it is first used to design and optimize two flat slabs in the structure, which was previously designed traditionally. Then it is applied to the design of the whole structure, considering seismic load. The model resulted in savings of 6.7-9% for the slab optimization compared to the original design, and 8.5% for the highrise structure optimization, compared to the original design. For highrise structures, these savings mean hundreds of thousands of dollars. This is the start of a new structural design software era, where the whole structural design is performed using an inclusive software that guarantees minimum time and cost for a structurally sound design.

Book Description
While the weight of a structure constitutes a significant part of the cost, a minimum weight design is not necessarily the minimum cost design. Little attention in structural optimization has been paid to the cost optimization problem, particularly of realistic three-dimensional structures. Cost optimization is becoming a priority in all civil engineering projects, and the concept of Life-Cycle Costing is penetrating design, manufacturing and construction organizations. In this groundbreaking book the authors present novel computational models for cost optimization of large scale, realistic structures, subjected to the actual constraints of commonly used design codes. As the first book on the subject this book: Contains detailed step-by-step algorithms Focuses on novel computing techniques such as genetic algorithms, fuzzy logic, and parallel computing Covers both Allowable Stress Design (ASD) and Load and Resistance Factor Design (LRFD) codes Includes realistic design examples covering large-scale, high-rise building structures Presents computational models that enable substantial cost savings in the design of structures Fully automated structural design and cost optimization is where large-scale design technology is heading, thus Cost Optimization of Structures: Fuzzy Logic, Genetic Algorithms, and Parallel Computing will be of great interest to civil and structural engineers, mechanical engineers, structural design software developers, and architectural engineers involved in the design of structures and life-cycle cost optimisation. It is also a pioneering text for graduate students and researchers working in building design and structural optimization.

Book Description
Abstract: The ultimate goal of any structural designer is not only to design safe structures that meet the requirements of the governing design Codes, but also to make sure that the design is cost effective and easy to construct. For medium- and high-rise structures, to achieve this goal, engineers mostly use steel and reinforced concrete as construction materials. For medium-rise structures, reinforced concrete two-way flat slabs offer a number of advantages over other systems, including their shallow depth, which can reduce the overall height of the structure or increase the effective story height. Due to fast constructability and shaping freedom, flat slabs are commonly used for parking structures, medium-rise buildings, large industrial structures, and warehouses. Thickness optimization of flat slabs lead to reduced sizes of beams, columns, and foundation system, and lower lateral demand on seismic lateral load resisting system. Moreover, thickness optimization generates savings in material and labor costs. This research explores an alternate design method (referred to as the Rational Design Method (RDM) in ASCE 7-16) that can be used to optimize two-way flat slabs, applied to re-design of an existing five-story concrete parking garage. This study presents an iterative design process, where the computer program Etabs-2016 was used for 3D modeling and analysis. The optimized design is compared with the original design of the existing City Hall Automated Garage building located in West Hollywood, California, designed using commonly used methods. The comparison between the original and re-designed building clearly demonstrates the advantages of the optimized design, as the total self-weight of the building was reduced by 30%.

Book Description
Reinforced concrete structures are one of the major structural types and must adhere to design regulation codes. It is ideal to find the best design (section dimension, material type, and amount of reinforcement) with the minimum cost providing the design constraints (design formulation considering loading of structure). Metaheuristic methods inspired by natural phenomena can consider design constraints by combining the analyses of formulation of reinforced concrete structures with an iterative numerical algorithm using several convergence options of random generation of candidate design solutions. Metaheuristic Approaches for Optimum Design of Reinforced Concrete Structures: Emerging Research and Opportunities is a pivotal reference source that focuses on several metaheuristic algorithms and the design of several types of structural members. Additionally, retrofit applications and seismic design issues are considered for readers in earthquake zones. Highlighting a wide range of topics including algorithms, design variables, and retrofit design, this book is ideally designed for architects, engineers, urban designers, government officials, policymakers, researchers, academicians, and students.

Book Description
Optimierungsgestütztes Entwerfen und Bemessen liefert neuartige Methoden, bewehrten Beton besonders effizient einzusetzen. Dabei wird die mathematische Optimierung auf die praktischen Probleme des Betonbaus angewendet. Ziel ist es, sparsam mit dem weltweit meistverwandten Baustoff Stahlbeton umzugehen und damit den CO2-Ausstoß aus der Zement- und Stahlherstellung und den Ressourcenverbrauch an Kies, Sand und Wasser substanziell zu reduzieren. Drei Themenbereiche sind angesprochen. Erstens, die Strukturfindung, also die Frage nach der richtigen äußeren Form, dass schlanke, nach dem Kraftfluss ausgerichtete Tragwerke entstehen. Baustoffgerecht sind sie weitgehend auf Druck beansprucht. Zweitens, die Bewehrungsführung, die sich am inneren Kraftfluss orientiert. Vorteile ergeben sich gerade für Scheiben, volumenartige Bauteile, an Lasteinleitungsbereichen und Aussparungen. Es entstehen anschauliche, direkt in Bewehrungen umsetzbare Fachwerkmodelle. Dritter Entwicklungsschritt ist die Behandlung von Querschnitten. Sie werden in ihrer Form optimiert und in ihrer Bewehrung bemessen. Dies gilt auch für anspruchsvolle Beanspruchungen (zweiachsige Biegung) und nahezu beliebige Formen. Eine Parametrisierung ermöglicht die allgemeingültige Übertragung auf ganze Klassen von Querschnitten. Die optimierungsgestützten Methoden werden vertieft und anschaulich beschrieben. Sie sind universell anwendbar und unabhängig von Normen, Betonarten und Bewehrungen. Sie gelten für normalfeste bis zu ultrahochfesten Betonen, für Bewehrungen aus Stahl, Carbon oder Glasfasern und für Bewehrungsstäbe als auch -fasern. Zahlreiche Abbildungen und Berechnungsbeispiele verdeutlichen die Anwendung. Zudem werden praktische Umsetzungen vorgestellt, darunter ultra-leichte Stahl-Beton-Balken, schlanke Solarkollektoren aus Beton und verbesserte Bewehrungslayouts für Tunnelschalen. Das Buch richtet sich gleichermaßen an Studierende, Forscher und Praktiker.
